Abstract
A wire electric discharge machine performs electric discharge machining on a workpiece by relatively moving a workpiece placed on a workpiece table and a wire electrode supported by upper and lower wire guides according to a machining program. The wire electric discharge machine comprises an interference determination unit configured to determine whether or not the top or bottom surface of the workpiece table interferes with the wire electrode at the height of the surface during the execution of the machining program.
Claims17
A wire electric discharge machine, comprising:
- a workpiece table;
- upper and lower wire guides;
- a wire electrode supported by the upper and lower wire guides, wherein the wire electric discharge machine is configured to perform electric discharge machining on a workpiece by relatively moving the workpiece placed on the workpiece table and the wire electrode supported by the upper and lower wire guides according to a machining program;
- and
- a processor configured to determine whether or not the top or bottom surface of the workpiece table interferes with the wire electrode at the height of the surface during the execution of the machining program.
An arithmetic device configured to virtually execute a machining program for causing a wire electric discharge machine, which comprises a workpiece table, upper and lower wire guides, and a wire electrode supported by the upper and lower wire guides, to perform electric discharge machining on a workpiece by relatively moving the workpiece placed on the workpiece table and the wire electrode supported by the upper and lower wire guides, the arithmetic device comprising:
- a processor configured to determine whether or not the top or bottom surface of the workpiece table interferes with the wire electrode at the height of the surface during the virtual execution of the machining program.
